Beyond the Titanic: The Real Science of Deep Sea Exploration

After five people perished on a controversial submersible dive to the wreckage of the Titanic in June, we got to thinking about what genuine undersea exploration looks like. In this episode, we speak with Tony Perrottet, who profiled the late OceanGate CEO Stockton Rush for Smithsonian magazine in 2019, about our ancient fascination with exploring hostile environments. Then we’re joined by Susan Casey, who has written four best-selling books about the ocean and its creatures, the newest of which is The Underworld: Journeys to the Depths of the Ocean. Susan tells us why understanding the ocean is key to humanity’s survival, and how, while serious research and shipwreck tourism may have some overlap, they remain two very different things.
